Looking and Saying things

I know it's not exactly abuse or anything but what does it count as if there is a certain family member of the opposite sex who keeps acting in a weird way towards me. Like he'll always make sexual comments about me and to me and it's nothing direct like 'let's have sex' but it's clear what the connotations are. I also notice him looking at certain parts of me in a kinda creepy way too. He's a lot older than me (I'm only 17 and he's in his fifties) but it's really creeping me out. I always feel uncomfortable in the same room as him, especially if we're alone in case he did try anything. The rest of the family just ignores it and treats it as if its normal, but I dont think its normal for a member of your family of the opposite sex who is a lot older than you to be like that. It's not just joking, you know?
I hope I'm not just being paranoid, but it's been going on since I was a kid. I know it's not like proper abuse or anything but it just creeps me out a bit.

that's totally inappropriate and no wonder you are creeped out. what an asshole. can you confront him? would you feel comfortable doing that? in the meantime don't be alone with him. it might be awkward but your safety is the most important thing.

if you can't confront him (and i totally understand that) then you will have to avoid him as much as possible. try and keep as much distance as possible between the two of you. come up with as many excuses as you can for why you can't see him or be alone with him. you don't deserve this. it's so fucked up and it's not fair to you at all to be put in this position. you're not the crazy one here.
